Comparing AWS cloud and on-premise data centers


Whenever an organization thinks of migrating their infrastructure over to a public cloud, the first question that strikes the organization is cost. AWS provides major advantages over on-premise environments as there is no upfront cost from using AWS. Thus, there is no CapEx requirement as AWS works on OpEx. That means a customer pays only on a monthly basis based on actual consumption of AWS resources.

The following table differentiates cost on various counts between AWS and on-premise environments:
